Correct Answer: EpidermisYour Answer: C
✅ Correct Answer: C — Epidermis
The Epidermis is the outermost layer of the skin. It is a protective barrier that prevents water loss, infection, and UV radiation damage. Epidermis contains Keratinocytes (produce keratin for protection) and Melanocytes (produce melanin for skin color). It has no blood vessels.
❌ Why other options are wrong:
• A. Dermis — Dermis is the middle/second layer of skin beneath the epidermis; contains hair follicles, sweat glands, blood vessels, and nerve endings.
• B. Hypodermis — Hypodermis (Subcutaneous layer) is the deepest layer of skin; mainly consists of fat and connective tissue for insulation and energy storage.
• D. Subcutaneous layer — Same as Hypodermis, the deepest layer; not the outermost.
📝 Important Note: Skin has 3 layers: Epidermis (outermost), Dermis (middle), Hypodermis/Subcutaneous (innermost). Skin is the largest organ of the human body. Epidermis has 5 sub-layers (strata). Melanin in epidermis determines skin color and protects from UV rays.
